What is Bitcoin?
Bitcoin is a decentralized digital currency that enables peer-to-peer transactions without the need for intermediaries like banks. It utilizes cryptographic principles and a distributed public ledger known as the blockchain to record and verify all transactions. Created by the pseudonymous entity Satoshi Nakamoto, Bitcoin was launched in January 2009 with the mining of its first block, called the Genesis Block. Its supply is mathematically capped at 21 million coins, making it a deflationary asset. Each bitcoin can be subdivided into 100 million units known as satoshis, allowing for micro-transactions and broad accessibility.
The Bitcoin network operates on a consensus mechanism called Proof-of-Work, where miners use computational power to validate transactions and secure the network. In return, they receive newly minted bitcoins and transaction fees. Users interact with the network through digital wallets, which consist of a public address for receiving funds and a private key that authorizes outgoing transfers. Bitcoin serves multiple purposes: as a medium of exchange for goods and services, a store of value similar to digital gold, and a speculative investment asset.
How Does Bitcoin Work?
The Blockchain Technology
At the heart of Bitcoin is the blockchain, a transparent and immutable ledger that records every transaction ever made. This technology ensures that all network participants agree on the state of transactions without relying on a central authority. Each block in the chain contains a set of transactions, and once added, it cannot be altered without consensus from the majority of the network.
Mining and Transaction Verification
Miners play a crucial role in maintaining the network’s integrity. They compete to solve complex mathematical puzzles, and the first to succeed gets to add a new block to the blockchain. This process not only verifies transactions but also introduces new bitcoins into circulation. The mining reward decreases over time through events known as "halvings," which occur approximately every four years.
Wallets and Keys
To use Bitcoin, you need a digital wallet. This software generates a pair of cryptographic keys: a public key (your wallet address) that you share to receive funds, and a private key that must be kept secure to authorize transactions. Losing your private key means losing access to your funds permanently.
Bitcoin Price Dynamics
The price of Bitcoin is determined by supply and demand dynamics in global markets. Its value against the US Dollar and other fiat currencies fluctuates based on factors such as market sentiment, regulatory news, institutional adoption, and macroeconomic trends. Unlike traditional currencies, Bitcoin operates 24/7, allowing for continuous trading and real-time price discovery.
Traders and investors use various tools to track Bitcoin’s price, including live charts, technical indicators, and market analysis. Its volatility offers both opportunities and risks, making it essential for participants to conduct thorough research and practice risk management.
Common Use Cases for Bitcoin
- Everyday Transactions: A growing number of merchants accept Bitcoin for payments.
- Store of Value: Many view it as a hedge against inflation and economic uncertainty.
- Investment and Speculation: Traders engage in buying and selling to profit from price movements.
- Remittances and Cross-Border Transfers: Its borderless nature facilitates low-cost international payments.

What determines Bitcoin’s price?
Factors like adoption rates, regulatory developments, market demand, macroeconomic trends, and technological advancements influence its price.
Can Bitcoin be hacked?
The Bitcoin network itself has never been hacked due to its robust cryptographic design. However, individual exchanges or wallets may be vulnerable if not properly secured.
Why is Bitcoin often called 'digital gold'?
Like gold, Bitcoin is scarce, durable, and perceived as a store of value. Its decentralized nature and resistance to censorship further reinforce this comparison.
